LABEL-ADVANCING MECHANISM.

T 0 all whom it may concern:

Be it known that we, JOHN EMANUEL JOHNSON and CHARLES H. OsLUND, said JOHNSON being a subject of the King of Sweden and said OSLUND, a citizen of the United States, both residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Label-Advancing Mechanism, Of which the following is a specification.

This invention relates to a pasting mechanism, and while capable of general use, it may be considered as an improvement over the pasting machine set forth in our application for Letters Patent filed October 22, 1915,'Serial No. 57 ,349, and is particularly adapted to be applied to the sameclass of 7 machines.

The principal objects of this invention are to provide the label holding mechanism with improved means for applying pressure to the labels and improved means for releasing the same so as to permit of filling the label holder readily; to provide improvements in the means label holding device; and "other improvements in the details of construction.

Reference is to be had to the accompanying drawings in which- Figure 1 is a side elevation of a labeling device constructed in accordance with this invention; r

Figs. 2 and 3 are end views of one of the weights for feeding the label holding plates showingthe locking device in two diife'rent positions;

Figs. 4 larged scale of and 5 are side elevations on enthe weights for feeding the 'label holders down and holding them in position; h

Fig. 6 is a plan of the end of the rack shown in Fig. 5, and

Fig. 7 is an end view of the label holder looking in the direction ofthe arrow 9 in The machine is shown as comprising a frame 42 having a stand 153 extending upwardly therefrom onwhich the label-holder is mounted. -On the top of this stand is a horizontally movable support 154 adapted to be held by a spring 155 in its forward operastng position against an adjustable sto Means for operating this not shown in Specification of Letters Patent.

full as it can be operated as in the above mentioned case by means of a swinging arm 196 and operating lever or fork-191; The bottom of the support 154 is provided with two lugs 197 so that the arm 196 positively operates the support 154 in both directions. On the top of this support is 157 on which a bracket 158 is mounted. This bracket is provided with an adjusting screw 59 for changing the height thereof.

Projecting upwardly bracket 158 are a pair of parallel rods 160. Between these rods are a series of cross bars 161, four being shown. They are adjustably fiXed in position on the rods 160 by means of set screws so as to be adjusted for labels of any desired width. Each of these cross bars has a plurality of guides 162 constituting one side of the label holder. They are also provided with arms 164 mounted wardly to hold the labels. They permit the labels to be withdrawn from between them as-in the above identified case.

The bracket 158 is provided with a rearward extension 172 on which is mounted a plate 174. This is connected with the rods a vertical stud I at an angle from the 160 by tie rods 173. The plate 174 is pro- H vided with a pair of guide rods 175 for sup porting rollers 177 which by means of weights 18 are held down onthe rods 175. The weights are provided with sockets 19 having springs therein. Each ofthese springs bears against the end of a rod 179.

which is guided 1n the socket and in a projection 20 on the weight. The springs normally press these rods down so that pins 21 thereon engage the ends of slots 22 in the projections 20. The rods 179 carry at their ends plates 180 adapted-to engage the end label in each label holder and hold thelabels therein in proper position against the hooks 171. The weights 18 hold the rods 179 down toward the hopper so as to keep the labels'in proper position.

-One of the guide rods 175 is shown as smooth on top, but the other is provided with a rack-24 {or receiving a pawl 25 carried bythe weight 18. This pawl is pivoted so as normally to engage the teeth of 'the rack and prevent the Weight being slid in Fig. 3 its prong 27 is capable of sliding:

ing down theguidie rod 175. This is the position the parts arebrought to when it is desired to withdraw the plates 180 for the purpose of filling the hoppers.

The normal position of this latch 26 is partwaybetween the .two positions shown in Figs; 2' and 3 so'that theprong 27 does notengage in the notch 29 and'the pi'0ng28 is also withdrawn from e-ngagement'with the pawl 25. In this position of the parts the pawl 25 engages its teeth and the late 180 is fed down by gravity, the Weig t of the member 18 serving to assist in moving it along.- It is to be noted however, that the plate or plunger 180 is yieldingly connected with this weight. p After the plunger has fed forward suiticiently and it is desired to refillthe hopper the latch 26'is swung around farther to the shown in Fig. 2 so that the prong 28 engages under the pawl25 and raises it away from its teeth. Then the Weight withits rod 179 and plate or plunger 180 can beslid along the rod'up to the end and the latch then turned over into the position shown in Fig. 3 to-permit offilling the hopper. V I

Mounted on the bracketBOcarried bythe stand 153 are adjusting screws 31 on which rests/the containing vessel or paste pot 223.

These screws can be adjusted to regulate the angle at which the paste-pot is located as 'For'the through apassage in the'stand 153' so that its beveled end comes over the lug 33 and" with aslantedplate53 to receive the drip position by pings from'abov'e and is held in two snap springs '54 and 55.

Although we have described the container 223 as a paste pot and referred to the other mechanismdesi-gned for the purpose of pasting labels, we are aware of the fact that this part of 'ClIlQflGVlCG either-in the form shown or other forms can be used for coating purposes in general, and that; it is l not necessarily limited to, pasting; e are .s also aware of the fact that; changes in the construction and design of the, parts can be made. without departing from the scope of the invention asexpressed in the claims.
